Description
Technical field
The present invention relates to technical field of heat exchangers, more particularly to a kind of three-dimensional deflection plate and shell-and-tube heat exchanger.
Background technology
Shell-and-tube heat exchanger is also known as tubular heat exchanger or shell and tube condenser, and it is applied to chemical industry, oil, doctor
" liquid --- liquid " in the industries such as medicine, food, light industry, metallurgy, coking, " vapour --- vapour ", the convection current of " vapour --- liquid " heat exchange
Heat transfer, and steam condensation and the heat exchange condensation flow such as liquid evaporation, are the heat exchangers being most widely used.
Shell-and-tube heat exchanger is typically made up of main members such as tube bank, housing, bobbin carriage, outer skulls, and tube bank is that shell and tube is changed
The core of hot device, tube bank is generally by heat exchanger tube, deflection plate（Or referred to as support plate）With tube sheet composition, rows of heat exchanger tube passes through
Deflection plate supports that its two ends is pierced into be connected in the pore of tube sheet with tube sheet, in the sealing for the joint for ensureing exchanger tubes and tubesheets
Property and intensity in the case of, you can as a tube bank, tube bank constitutes complete heat exchanger with housing, bobbin carriage again.Wherein, exchange heat
Pipe determines the heat transfer property of tubular heat exchanger as heat conducting element together with deflection plate, and bobbin carriage then determines shell and tube with housing
The bearing capacity of heat exchanger and the security reliability of operation operation.The manufacturing process of this shell-and-tube heat exchanger is ripe, security
Can be high, it is crucial energy consumption equipment in heat transmission equipment.
In conventional art, the structure of the commonly used deflection plate in tube bank is generally segmental baffle, or in arch folding
Discount vibram outlet blocking solution shape deflection plate, ring disk and doughnut baffles, orificed plates, rod baffle being improved on the basis of stream plate etc., these
More or less all there is following weak point in baffle arrangement：(1) because flow direction is varied multiple times in shell-side fluid, easily exist
Deflection plate edge produces fluid separation, so as to increase flow resistance；(2) between segmental baffle and housing between there is stream
Dynamic stagnation dead band, heat transfer efficiency reduction is not only resulted in, and the fluid in stagnation dead band is easy in shell-side fouling；(3) for discount vibram outlet
Blocking solution shape deflection plate, because fluid flows in the tube axial direction parallel to heat exchanger tube in discount vibram outlet area, causes heat transfer property to decline；
(4) for ring disk and doughnut baffles, multiple baffling of the shell-side fluid through deflection plate can produce distributary flowing, and then be conducted heat reducing
Mean temperature difference；(5) when shell side import and export pipe away from tube sheet farther out when, flowing stop zone can become big, guide shell need to be set up, also
The effective length of heat exchanger tube must be increased；(6) for deflection rod heat exchanger, it is hardly formed effectively in highly viscous medium
Toll bar vortex, and then do not reach the requirement of high heat transfer efficiency.
The problem of existing for traditional deflection plate, the countermeasure that people take is to cast off segmental baffle once and for all, using spiral shell
Revolve flat tube and self support heat exchanger tube, or heat exchanger tube self is supported using winding pipe, or two-dimentional deflection plate is combined into helical baffles
Heat exchanger tube etc. is supported, the deflection plate of these improved structures also brings use condition while above-mentioned subproblem is solved
The problem of limitation, the complexity of structure, non-easy cleaning and maintenance, cost height etc. are new.In addition, with petrochemical plant
Large-scale development and power-saving technology index it is perfect, the applicable nominal diameter of shell and tube exchanger is expanded to from 2600mm
4000mm, the Enlargement Design of physical dimension can't natively bring the technological effect that linear scale increases, and can amplify original on the contrary
Some shortcomings, for example, in the shell and tube exchanger of big nominal diameter, existing baffle arrangement（Including traditional deflection plate
With the existing deflection plate after improvement）, a portion is not suitable for the shell and tube exchanger of big nominal diameter in itself, wherein separately
A part make it that the above mentioned problem itself existed is more prominent and serious.Therefore, for above-mentioned problems and defect, research and development one
Kind lamps structure is simple, the deflection plate and shell and tube exchanger that designing technique is reliable, manufacturing process is ripe, infrastructure cost is low, its energy
Effective heat exchange area and heat exchange efficiency are enough improved, there is important engineering significance to steady production and economic benefit.

In movable tube sheets heat exchanger or fixed tube-sheet exchanger, the heat exchanger that shell-side fluid is liquid or gas is applied also for, and
It is particularly suitable for use in the shell-and-tube heat exchanger of major diameter, low flow velocity or both.When the He of shell side inlet tube 11 of the sidepiece of housing 1
Shell-side outlet pipe 12 all away from tube sheet farther out when, using above-mentioned three-dimensional deflection plate, in this way it is no longer necessary to set up guide shell, you can pass through
The auxiliary body guiding fluid of baffling reaches the back side of tube sheet, and then simplifies heat exchanger structure.In addition, for traditional heat exchanger, only
Tube bank therein need to be changed（Tube bank includes heat exchanger tube, deflection plate and tube sheet）, you can the heat-transfer effect for enhancing heat exchanger is reached,
And then improving heat exchange efficiency, so that the technology upgrading of heat exchanger is easy to operation, and cost input cuts energy-conservation effect less
Fruit is significantly.
